(Cl. 12S-33) 8 Claims.

Our invention relates to a vibrator that is electrically operated forvibrating a human body by ythe person standing on a platform that isvibrated electrically and the objects of our invention are:

First, to provide a body rvibrator of this class which is very small andcompact so that it may be readily used in a bathroom, bedroom or thelike the same as scales;

Second, to provide a body vibrator of this class by the use of which theperson to be treated stands upright on a platform and the platform isvigorously vibrated, thus vibrating the whole body of the person;

Third, to provide a vibrator of this class in which the platform issecured directly to the. one side of a laminated armature;

Fourth, to provide a body vibrator of this class in which the platformis supported resiliently at one end upon a resiliently supported baseand is supported on its other end on a laminated armature for anelectro-magnet;

. Fifth, to provide a body vibrator of this class in which theelectromagnet and armature are supported and positioned on an openbracket in cushioned relation with said bracket and with each other; and

Sixth, to provide a body vibrator of this class which is Very simple andeconomical of construction, easy to operate, efficient in its action andwhich will not readily deteriorate or get out of order.

With these and other objects in View as will appear hereinafter, ourinvention consists of certain novel features of construction,combination and arrangement of parts and portions as will be :i

hereinafter described in detail and particularlyset forth in theappended claims, reference being had to the accompanying drawing and tothe characters of reference thereon which form a part of thisapplication in which:

Figure 1 is a top or plan View of our body vibrator and showing a covercasing in section taken from the line i-l of Fig. 2; Fig. 2 isalongitudinal sectional View taken from the line 2--2 of Fig. l; Fig. 3is an end view just inside of one side of the casing taken from the line3 3 of Fig. 2; Fig. 4 is a sectional view taken from the line 4-4 ofFig. 2 and Fig. 5 is an enlargedr fragmentary sectional view taken fromthe same plane as Fig. 2.

Similar characters of reference lrefer to similar parts and portionsthroughout the several views of the drawing:

The base member i, platform member 2, platform and base connection 3,,platform supIJOrting 55 bracket 4, electro-magnet winding 5, electromagnet laminated core S, electro-magnet laminated core adjusting bolts 1,laminated armature 8, laminated armature cushion envelope 9, electricconductors it and cover casing El constitute the principal parts andportions of our body vibrator.

The base member I includes a substantially rectangular shaped plateportion la provided with a central hole ib and with an upwardlyextending ledge Ic along its back side. It is provided with twobackwardly extending channel members ld and le at its opposite sideswhich terminate with a cross bar lf which extends across the back endand preferably integral with the members id and le, and this base memberis supported by means of a plurality of rubber cushions I c, one at eachcorner and two intermediate the ends at the opposite sides.

Mounted centrally over the opening lb on the portion la of the basemember I is the platform supporting bracket 4 which is provided with abase portion la which is secured to the portion la by means of screwbolts 4b.. It is provided with a central openingr lic and above thisopening with a backwardly extending ledge 4d, shown best in Fig. 2 andwith opposite end walls 4c.

Mounted on the base portion 4a of the bracket 4 and positioned centrallyis the laminated armature 8 which is provided with a non-inflatablecushion covering in the form of an envelope, preferably soft rubber,designated 9 and including a substantially heavy base portion 9a belowthe armature 8 provided with grooves Sb in its upper surface on which torest the lower side of the armature 8. At its upper side it is providedwith a relatively thin cover portion 9c which is corrugated at its upperside at 9d. Corrugations 9d are also provided at the lower surface ofbase portion 3a as seen in Figs. 4 and 5.

Positioned adjacent to and above and preferably resting on thiscorrugated portion 9d of the cushion 9 is an electro-magnetic laminatedcore 6 which is provided with a central portion 6a and with two sideportions 6b and lic and wound around the central portion lia of thiscore 6 is an electro-magnet winding 5 which is wound through the opening5a at one side and this winding 5 is connected electrically with asource of electrical energy to the electric conductors Il), which sourceof electrical energy is not shown. The core 6 is supported on thebracket 4 by means of bolts Ed which are mounted in slotted holes 4f inthe bracket 4 which permit the shifting of the bolts upwardly anddownwardly. These bolts pass through the core 6 as shown best in Fig.2.0i the drawing. This core is also supported by means of clamp platesSe which are supported by bolts Gf extending through the bracket 4.

Screw threaded in the ledge 4d of the casing 4 are adjusting bolts 1.Their extended ends are adapted to rest against the upper side of thecore '6 and are adapted to press the core 6 downwardly adjacent thecushion portion 9c and this provides adjusting means for adjusting thevibration strokes to provide the best results. These bolts 'I areprovided with lock nuts la for holding the bolts from turning after theadjustment is made.

Mounted in the laminated armature 8 are two bolts 3a which are screwthreaded into the solid end portion Za of the platform member 2. portion2a is provided with an extended flange portion 2b which extends underthe armature 8 some distance and rests upon the rubber cushion 9, shownbest in Fig. 2 of the drawing.

Extending from the portion 2a backwardly on Extending backwardly fromthis portion 2e is a rectangularly shaped portion 2f of the platform 2.It is provided on its upper surface with a knurled portion outlined bythe lines 2g, shown best in Fig. l of the drawing. This platform portion2 f is provided with a downwardly curved portion 2h which is providedwith an angular beveled portion 2z on its lower side to which is securedplatform base `connection 3 by means of screws 3a. This connectionmember 3 is provided with an angular forwardly extending portion 3bwhich extends forwardly in a groove so that it is flush with the lowerside of the member lf. This portion 3b is secured by means of screws 3C.This member 3 is preferably made of spring material which permitsvibration movement of the platform 2 vibrated by the laminated armature8 in cooperation with a vibrator including the core 6 and winding 5 andcushioned by the cushion member 9 surrounding the laminated armature 2and positioned between it and its base and between it and the core 6.

Positioned over the portion la of the base member l and over thevibrating apparatus and enclosing the same is a cover casing I I whichis open at its lower side and adapted to fit around the portion la andextend backwardly of the ledge lc and only extends downwardly at theback side to neal` the platform member 2, all as shown best in Fig. 2 ofthe drawing.
